Farewell to Reality: How Modern Physics Has Betrayed the Search for Scientific Truth

From acclaimed technology writer Jim Baggot, a pointed critique of contemporary theoretical physics.

In this wonderful new quantity, Jim Baggott argues that there's no observational or experimental facts for lots of of the information of recent theoretical physics: super-symmetric debris, large strings, the multiverse, the holographic precept, or the anthropic cosmological precept. those theories will not be purely unfaithful; they don't seem to be even technological know-how.

They are fairy-tale physics: fantastical, strange and sometimes outrageous, even perhaps confidence-trickery. This publication offers a much-needed antidote. educated, accomplished, and balanced, it bargains lay readers the newest rules concerning the nature of actual truth whereas basically distinguishing among truth and myth.

With its enticing snap shots of many critical figures of recent physics, together with Paul Davies, John Barrow, Brian Greene, Stephen Hawking, and Leonard Susskind, it can provide to be crucial analyzing for all readers drawn to what we all know and don't learn about the character of the universe and truth itself.

For the Love of Physics: From the End of the Rainbow to the Edge of Time - A Journey Through the Wonders of Physics

Universally praised for the remarkably enjoyable, creative, and infrequently wacky ways that Walter Lewin brings the thrill of physics to life—from super-charging a tricycle with a hearth extinguisher to risking his existence by way of placing his head within the course of a swinging wrecking ball—For the affection of Physics takes readers on a fabulous trip, starting our eyes as by no means earlier than to the superb good looks and gear of all that physics can divulge to us, from the good, most eldritch positive aspects of the tiniest bits of subject, to the wonders of our daily lives.

Atmospheric science

Wallace and Hobbs' unique version of Atmospheric technological know-how helped outline the sector approximately 30 years in the past, and has served because the cornerstone for many college curriculums. Now scholars and pros alike can use this up-to-date vintage to appreciate atmospheric phenomena within the context of the most recent discoveries and applied sciences, and get ready themselves for extra complex research and real-life challenge fixing.

Mössbauer Spectroscopy in Materials Science

Fabric technology is among the such a lot evolving fields of human actions. Invention and consequent creation of latest fabrics for functional and/or technological reasons calls for as whole wisdom of the actual, chemical, and structural homes as attainable to make sure right and optimum utilization in their new positive aspects.

Example text

We take a universal hypothesis H, say 'All ravens are black', and some suitable universe of discourse. We divide the latter, first into the class R of ravens and the class R' of non-ravens, and second into the class B of black objects and the class B' of non-black objects; which gives us four intersection classes: (1) (2) (3) (4) RB RB' R'B R'B' Hempel showed that instances of (3) and (4) are on a par, confirmation-wise, with instances of (1): if Ra 1\ Ba instantiates 'f/x(Rx -+ Bx), so does - Rb 1\ Bb instantiate the logically equivalent hypothesis 'f/x(-Rx v Bx).

But it also has a great disadvantage. Let T be a theory whose development for E is mathematically precise. Then, given that there are limits to observational accuracy, there will be another possible theory, say T', whose development for E is equally precise and observationally indistinguishable from but logically inconsistent with that of T. Now E (which we assume to be self-consistent) obviously cannot logically imply both developments, since they are mutually inconsistent; nor can E favour one of them, since they are observationally indistinguishable.

In other words, they denied that a universal scientific hypothesis is a true-or-false description of the world and re-interpreted it as an inference-ticket that licenses us to infer new singular observationstatements from suitable sets of old ones. Precious little of the Bacon-Descartes ideal survives in that view of science. ) The pattern of the foregoing development seems to have been this. Some approximation to scientific certainty was desired. But it was recognised that science, interpreted realistically, is enormously topheavy relative to its empirical base: so it needed to be cut down to a manageable size so that it could then be adequately supported by its base.
